 Prof. A. S. Hitchcock presided. The following scientific program was

William A. Dayton : Collecting data on National Forest range plants. 

 For nine years past the Forest Service has conducted a study of the dis- 

 tribution, natural habits, and economic importance of its range flora. 

 Approximately 35,000 plant specimens, representing about 4,800 species, 

 have been collected on National Forests and Purchase Areas. Ecologi- 

 cal and economic data have been furnished by the collectors of most of 

 these specimens, and this material has been supplemented by much 

 detailed data procured by grazing experts of the Service. The speci- 

 mens have been identified by experts of the Bureau of Plant Industry. 

 Economic notes are compiled in the Washington office and distributed 

 among Forest officers. These data have application to many phases of 

 range-management, e.g., intensive range-utilization especially with a 

 view to minimum interference with the requirements of the important 

 forage plants, and the utilization of each type at the time and by the 

 class of stock to which it is best adapted; detection, eradication, fenc- 

 ing, etc. of poisonous-plant areas; natural range reseeding; studies in 

 carrying capacity, plant indicators, plant succession, artificial reseeding, 

 etc.
